There are all kinds of people who are Christian. Their worldviews and interpretations are as varied as anyone else. Most of the ones I know aren’t the type to go cherry picking passages to use as an excuse to mistreat others. Many quietly lead their lives as an example of Christian faith. It’s often acknowledged among Christians that no one - Christian or otherwise- is perfect and no one but God can judge others.
There are others who didn’t get that memo. They take it all very literally. It’s like they completely missed the point of the four gospels in which one of the themes is Jesus at odds with the Pharisees who are so stuck on the Old Testament that they forget love and compassion. It’s not that the New Testament contradicts the Old Testament so much as it’s teaching that going through the motions and following the rules exactly as written is not the same as living with God and showing humanity towards others.
In my experience, this latter group is often comprised of people who grew up being taught strict adherence to the Bible, with a particular focus on the Old Testament, and born again types whose rigid compliance keeps them on the straight and narrow.
Not all Christians are Republicans or conservative. You really have all types, from the ones you’re talking about to some pretty liberal, polar opposite ones. Some identify with conservative politics because of their Christian views and others are avowed liberals for the same reason.
Most of the Christians I know are good people, and their happiness and just how they live their lives is something you want for yourself. They lead by example. I’ve been around the other ones too and I’m not particularly fond of hanging out with them. Ironically, those were the ones whose outward attitudes and behavior in private were completely contradictory. Basically, they were the kinds of people you probably don’t want to be around regardless of religion.
What a loser. World’s richest man my ass. This bum doesn’t even pay his bills.
